Narrative:
Got off airway (V409) centerline by about 10 mi, and was slow getting up to assigned altitude on an IFR flight plan. Both problems were reported to me by ATC. Problem was due to a temporary higher than usual workload: autoplt and DME were lost (temporarily) at the same time while climbing near an intersection requiring a course change. ATC issued a vector back on course, altitude was maintained, no further problems with flight. Recurrence of similar sits could be prevented by promptly asking ATC for navigational assistance.

Narrative: GOT OFF AIRWAY (V409) CTRLINE BY ABOUT 10 MI, AND WAS SLOW GETTING UP TO ASSIGNED ALT ON AN IFR FLT PLAN. BOTH PROBS WERE RPTED TO ME BY ATC. PROB WAS DUE TO A TEMPORARY HIGHER THAN USUAL WORKLOAD: AUTOPLT AND DME WERE LOST (TEMPORARILY) AT THE SAME TIME WHILE CLBING NEAR AN INTXN REQUIRING A COURSE CHANGE. ATC ISSUED A VECTOR BACK ON COURSE, ALT WAS MAINTAINED, NO FURTHER PROBS WITH FLT. RECURRENCE OF SIMILAR SITS COULD BE PREVENTED BY PROMPTLY ASKING ATC FOR NAVIGATIONAL ASSISTANCE.
